Method and data processing system having dynamic profile-directed feedback at runtime

摘要

According to a method of operating a data processing system, software communicates to a processing unit a classification each of at least one schedulable software entity that the processing unit executes. A resource manager within the processing unit dynamically allocates hardware resources within the processing unit to the schedulable software entity during execution in accordance with the classification of the at least one schedulable software entity. The classification may be retrieved by the software from in data storage, and operating system software may schedule the schedulable software entity for execution by reference to the classification. The processing unit may also monitor, in hardware, execution of each of a plurality of schedulable software entities within the processing unit in accordance with a monitoring parameter set among one or more monitoring parameter sets. The processing unit may then report to software the utilization of hardware resources by each of the plurality of schedulable software entities so that the software may develop or refine a classification for the schedulable software entity.
